Enable pca954x idle_disconnect to avoid possible I2C device address conflict.
How I did it
Change pca954x device_attr idle_state to -2 (MUX_IDLE_DISCONNECT).
How to verify it
Cat pca954x device_attr idle_state and confirm the value is -2.

I2c burst read may failed due to misoperation of ir3570a(A DC-to-DC converter IC).
As #2966, there are 3 more models have this symptom, as7326-56x, as7726-32x, and as9716-32d.
Also correct typo of naming on as7816-64x and as7716-32x.

What I did
Disabling i2c function of ir3570a which may failed i2c tranfer to others.
Close channel of mux after data transfered.
How I did it
Identify version of ir3570, if it's ir3570a, disable its alias i2c address.
Enable parameter of driver i2c_mux_pca954x to close channel on after every access.
How to verify it
Write 08 to offset 0xcf of systom eeprom and execute i2c block read.
It will return error.
plug-in several transceivers and run "show interfaces transceiver presence" and "sfputil show presence". You may see the different result. (But doing this requires updated xcvrd).
